Letters Patent No. 114,064, dated April 25, 1871.

IMPRovEMi-:N'r IN DRAWING-FRAMES.

The Schedle referred to in these Letters Patent and making part of thetime.

' ing-Frames and other machines in .which the sliver is traversed; and Ido hereby declare that the following lis a correct description ofrthegsame, reference being had to the accompanying drawing making partofv this specification, and to the letters of reference marked thereon.i

Figure 1 is a plan.

Figure 2 is an end elevation.

Figure 3 is a side elevation.

Figure 4 is a view of top and bottom rolls of a drawing-frame, showingthe b0sses,where the weight is applied, 85e.

In all the drawing-frames with which -I am acquainted the sliver-guidesare fixed to the traversingbar, and they are usually upon one rod orbar, in which latter case the weight will not bear equally upon theslivers, for by reference to iig. 4 it will be seen that when one sliveris at a, under one boss, it is very near the weight, while the sliver tothe other boss is at b, or furthest from it, and consequently has theleast weight to support, having the longest arm ot the lever.Manufacturers have been desirous of' obviating this diliicnl-ty, andcontiivances have been resorted to for effecting this object.

By my invention I produce a combination which is inexpensive,easy-working, operates very perfectly, and takes but little rooln.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

The heart A, which, unlike a crank, gives a uniform motion to thetraversing-rods, the worm-wheel B,.and worm C are as they are usuallymade ondrawingframes.

In practice "a toothed wheel is placed on the wormshaft in place of thehand-wheel ou the-drawing, and gears into another wheel on the back rollot' the draw-` ing-frame and is driven by it.

The rod E, which usually is nearly the length of the drawing-fram e, oris connected with another single traversing-har which is so, has xedguides upon it, but by my arrangement is connected with a shortcrossbar, H, which is pivoted in the center by the stud I, and. connectswith the two traversing-bars or Arods L M, which have adjustablesliver-guides N O fastened to them, and which must travel in oppositedirections.

The distance traversed by the rods L M is regulated by means of theslotted part F and the pin G.

The part F is secured to the end of the rod E, and its motion isgoverned by the throw of the heart A; but the pinG is adjustable iu theslot g in the crosshar H, and by this means the traverse of' thesliverguides is governed; for whenp'in Gis fixed nearer the' center orpivoting-stud `I ofthe cross-bar H the traverse will be increased, andwhen fastened toward the other end of lthe slot it will be diminished.

The arms J and K, at their upper parts, are secured to the guide-rods Land M, and at their lower extremities they are coustructed'so as to playfreely in slots in the ends of the cross-bar H, thus accommodatingthemselves to the arcs which the cross-bar makes as it turns upon itspivoting-stud I.

The sliver-guides are.usually made of two pins fixed viu atraversing-bar, but by my invention are made adjustable on the4 rods,and this, I believe, is one of the mostuseful features of my invention.

The stands P are for supportingr the traverse-rods, and are so made thatthe rods 4L and M will lslide freely through them.

On the drawing-frames the rods L M are extended so as to traverse theguides for all the bosses to the back rolls of the drawing-frame. Thedistances from center to center of the bosses are greater than fromcenter to center of the guides on the drawing, and suchy thatthe-sliver-guides can all be in a line between the two rods, eachsliver-guide being turned half-way round from the position shown.

I do not claim moving the sliver-guides together to the center oftherolls and afterward receding from it, as that has been patentedbyThomas Winn nu the 6th of September, 1870; but, not being aware that anymechanism has ever been shown for traversing onehalf thesliver-guides'in an opposite direction from the Vother half, withuniform speed, with adjustable sliverguides, and-a governor of thetraverse, so as to avail of the wear ou the whole length of the bosses,whether long or short,

What l claim as my invention, and desire to secure by Letters Patent, is

The mechanism herein described, consisting of the combination of theheart A and rod B, the slotted part F, the adjustable pin'G, thecross-bar H -pivoted in the center, the arms J and K, the rods L and M,the adjustable sliver-guides N and O, substantially as described. v
